Compressor removal
(1)
Tag and remove leads.
WARNING
Serious injury could occur if heavy equipment is moved/lifted without sufficient
personnel to do the job. Use proper physical lifting procedures or use a suitable
lifting device or dolly. Wear safety shoes, gloves and other suitable protective
clothing.
WARNING
DO NOT LIFT without holding unit in upright position. Otherwise, unit will fall over
and could cause injury to personnel.
NOTE
The compressor is mounted to the casing base by four cap screws that are inserted
from the underside of the base. In order to remove the compressor, it is necessary
that the entire air conditioner be raised and placed on blocks of sufficient height to
allow access to these bolts from below the base.
(2)
Attach an overhead hoist to the four lifting rings on each side of the cabinet, using two slings
and a spreader bar.
(3)
Raise the cabinet and place it on blocks at least four inches high. Be sure the blocks do not
obstruct the holes in the base through which the compressor mounting cap screws must be accessed.
WARNING
All refrigerant -22 must be discharged from system before attempting to remove
compressor.
(4)
Discharge the refrigeration system per para. 5-3.
(5)
Unwrap the insulation from the suction tube so the joint at the compressor is exposed.
